GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 323,903, dated August 11, 1885.

Application tiled March 16, 1885. (No model.)

To @ZZ whom it may concern:

Be it known that I, HoRATIo J. BREWER, ofthe city, county, and State of New York, have invented a new and useful Improvement in Galvanic Batteries, of which the following is a full, true, and exact description, reference being had to the accompanying drawings.

This invention relates to an improvement on the carbon-zinc battery, and is especially designedfor a battery in which a strong electro-negative element is employed in combination with carbon, though this is not essential to my invention. In thi-s battery the zinc is placed within a hollow carbon.

My invention will be readily understood from the accompanying drawings, in which Figure l represents avertical section; Fig. 2, a horizontal section through Fig. l on the line xx,- Fig. 3, a view of one of the sections of my hollow carbon;

A represents the cell, provided with cover B, which I prefer to use to support my carbon element; but it is not essential.. My zinc is placed in the center ofthe battery, and is shown at G, and is provided with asuitable connecting-screw, J. It is prevented from cont-act with the surrounding carbon by washers E H, of any suitable material.

The carbon element consists lof a number of hollowconical sections adapted to fit into each other,as shown at C. These sections are made corrugated on their interior surface, as shown at M, Fig. 3,V thereby allowing the passage of the exciting-liquid between them. Ihe upper section, N, is made longerthan the oth.

ers and somewhat different in shape, and projects above the cover, as shown.

Attached to and surrounding the sections G are the electro-negative plates or disks F, which may be made of the well-known Leclanche. compound of carbon and peroxide of manganese, or they may be made of carbon alone, or of any other suitable electro-negative element. Being made conical inside, they t rmly on the outer surfaces of sections C, making irm contact therewith. The battery is readily made up by placing the sections G one upon the other in the manner shown, when, with the exercise of a little pressure, a iirm contact is insured. The zinc,being placed in the center of this battery, is in immediate proximity to the carbon, and hence the internal resistance is low. The zinc likewise comlmunicates with the external liquid at sufficient intervals by reason of the corrugations described. The parts of this battery are readily replaced, and if the disks F become worn out in use they are readily replaced by others' without destroying the entire battery.

It is apparent that my battery would'be operative without the disks F; but I prefer to use them. A

What I claimas myinvention, and desire to secure by Letters Patent, is

1. rlhe improved electro-negative element shown, which consists of a series of hollow conical bodies placed one upon the other to form a single element, substantially as described. 2. The limproved electro-negative element shown, which consists of the hollow conical bodies C, provided with the electro-negative disks F, substantially as described.

3. The combinationiof two or more tubular carbon bodies, C, having interior corrugated surfaces, substantially as described.

4. The combination ofthe separable annuvlar carbon bodies C C G, forming a single ele- IIORATIO J. BREWER.
